The bulk of the DR 8 spectroscopy is made up of main-sequence stars and red giants that were targeted as part of the Sloan Extension for Galactic Understanding and Exploration (SEGUE) Survey, therefore the number of new spectroscopic WDMS binaries in DR 8 is very small compared to previous ...
接下来我们给出PAF在前瞻性研究中的计算公式如下:Population Attributable Fraction (PAF) = (proportion of cases exposed) x (attributable proportion in the exposed)或者: 在上面的公式中,Ppop 为总人群暴露率,RR是风险比。总人口暴露率在我们刚刚的例子中就是10000/100000=0.1风险比就是两个风险的比,暴露组风...

(2006) mapped a grain size locus, gw8.1, on chromosome 8 in BC3F3 population. Similarly, Liu et al. (2009) mapped two QTLs, qspp1, qspp11 and Luo et al. (2013) mapped qSPP5, respectively, for spikelet number per panicle in ILs and BC5F4 population. Gaikwad et ...
The association mapping population was analyzed for possible population structure with the model-based program Structure 2.2 [43] for the 91 rice accessions using a length of burn-in period and the number of iterations set at 10000 and a model allowing for admixture and correlated allele frequencie...
